Abstract
Description
Technical Field
[0001] The present application relates to the field of prism technology, and in particular to a prism coating fixture assembly. Background Art
[0002] The periscope camera is a key factor in improving the zoom ratio of mobile phone cameras. Its principle is simply to add a prism (or mirror) to allow the incident light of the lens to be reflected once or multiple times, utilizing the horizontal space inside the mobile phone, so that the mobile phone can be equipped with a telephoto lens without changing its vertical thickness.
[0003] The prism is a new component added to the traditional camera by the periscope camera. The prism processing technology has as many as dozens of steps to accurately refract the light into the imaging lens. The processing flow mainly includes rough grinding, fine grinding, polishing, chamfering, coating and silk screen printing. The prism used for the periscope camera is very small in size, and there are very high requirements for the control of precision and tolerance. At the same time, the light after refraction and reflection cannot be dispersed, and the prism supplier needs to have strong coating technology. Coating is a key link in prism manufacturing. The prism coating method is an important optical thin film preparation technology. By controlling the thickness and refractive index of the film, the light path can be controlled and adjusted.
[0004] In the related art, for the coating of prisms, the prism is generally placed in a jig, and then several jigs are stacked together and placed in a coating machine for coating. However, since the jig is universal, that is, it needs to be transported to other processes for use, the specifications of the jig are relatively small and the bottom surface is relatively flat, so it is not very stable when stacked. Therefore, in order to ensure stability, only a small number of jigs can be stacked together and used, and the coating efficiency is low. Utility Model Content

[0033] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0034] In the related art, for prism coating, the prism is generally placed in a jig, and then several jigs are stacked together and placed in a coating machine for coating. However, since the jig is universal, that is, it needs to be transported for use in other processes, the specifications of the jig are relatively small and the bottom surface is relatively flat, so it is not very stable when stacked. Therefore, in order to ensure stability, only a small number of jigs can be stacked together and used, and the coating efficiency is low.
[0035] To solve the above technical problems, please refer to Figure 1 The present application proposes a prism coating fixture 300 assembly, comprising a plurality of base assemblies, wherein the plurality of base assemblies are stacked vertically in sequence, and the base assemblies include:
[0036] The first base 100 is arranged in a frame shape and has a supporting surface 101 facing upward. The frame shape is a polygonal frame, such as a rectangular frame, a pentagonal frame, a hexagonal frame, etc. The embodiment of the present application is exemplarily described as a rectangular frame.
[0037] The second base 200 is arranged on the inner wall of the first base 100 and at least partially protrudes from the bearing surface 101. The second base 200 is arranged in a frame shape and encloses an installation cavity 200a, that is, the second base 200 is attached to the inner wall of the first base 100. The second base 200 can be arranged to partially protrude from the bearing surface 101, or to completely protrude from the bearing surface 101. The specific setting can be based on actual conditions, and the second base 200 can be integrally formed with the first base 100, or can be connected by screws. Through integral molding, the stability of the connection between the first base 100 and the second base 200 can be ensured. When connected by screws or the like, when the first base 100 or the second base 200 is damaged, only one of them needs to be replaced.
[0038] The jig 300 is arranged in the mounting cavity 200a and is detachably connected to the second base 200. The jig 300 is formed with a hollow groove 300a for placing the prism. Through the detachable connection, different jigs 300 can be easily replaced, and different jigs 300 can correspond to hollow grooves 300a of different specifications, that is, by replacing the jig 300, prisms of different specifications can be coated.
[0039] In an embodiment of the present application, when multiple base assemblies are stacked, the bearing surface 101 of the first base 100 contacts the bottom wall of the first base 100 of the adjacent base assembly, and the inner side wall of the first base 100 fits with the outer side wall of the second base 200 of the adjacent base assembly, that is, the bearing surface 101 and the outer side wall of the second base 200 form a step-like structure, and the lower surface and the inner side wall of the first base 100 located above also form a step-like structure. By combining the step-like structures of the two adjacent base assemblies, the stability of the stacked base assembly can be ensured, thereby reducing shaking and dislocation during the coating process and improving the coating quality.
[0040] Compared with the related art, which directly stacks the jig 300, the embodiment of the present application increases the strength of the entire structure by setting the cooperation between the first base 100 and the second base 200, and can stack more base components, thereby being able to stack more jigs 300, that is, being able to place more prisms, so that multiple prisms can be coated at one time, thereby improving the efficiency of prism coating.
[0041] In some embodiments, see Figure 1-2 The first base 100 can be a group of opposite side walls with a first avoidance groove 10a, or two groups of opposite side walls with a second avoidance groove 200b, which is not limited in the embodiment of the present application, and the second base 200 has a second avoidance groove 200b on the corresponding side wall, and the second avoidance groove 200b connects the first avoidance groove 10a and the installation cavity 200a.
[0042] That is, by setting the first avoidance groove 10a, the stacked jigs 300 can be spaced apart, so that when disassembling the jig 300, the base assembly of the upper layer can be conveniently removed, and the second avoidance groove 200b and the first avoidance groove 10a are both connected to the installation cavity 200a, which can facilitate the user to remove the jig 300.
[0043] Furthermore, vertically, the bottom height of the second avoidance groove 200b is lower than the height of the lower surface of the jig 300, that is, there is also a gap between the second avoidance groove 200b and the jig 300. Through the gap, the user can reach under the jig 300 through the second avoidance groove 200b and the gap, thereby making it convenient for the user to remove the jig 300 from the mounting cavity 200a.
[0044] See also Figure 3 The fixture 300 includes a main body 310 and a plurality of support plate groups 320. The main body 310 is formed with a plurality of placement holes 310a extending along the first direction XX. The plurality of placement holes 310a are arranged at intervals along the second direction YY. In this way, each fixture 300 can place a plurality of strip-shaped prisms.
[0045] Multiple support plate groups 320 are respectively arranged in the placement holes 310a. The support plate groups 320 include two support plates. The two support plates are respectively located on a group of opposite side walls corresponding to the placement holes 310a. The two support plates are arranged at intervals along the first direction XX. In this way, the contact area of the prism can be reduced, thereby reducing the contact area to avoid edge chipping and scratches. On the other hand, reducing contact can reduce the dirt ratio, thereby effectively protecting the prism.
[0046] by Figure 3 As shown, the first direction XX and the second direction YY are perpendicular to each other and are arranged in a rectangular frame on the first base 100. The first direction XX can be the length direction of the first base 100, and the second direction YY is the width direction of the first base. Of course, it can be understood that the first direction XX can also be the width direction of the first base 100, and the second direction YY can be the length direction of the first base 100. No further restrictions are made here.
[0047] See also Figure 3 In some embodiments, a supporting block 301 is provided on at least one side wall where the placement holes 310a are spaced apart along the second direction YY. The supporting block 301 protrudes from the side wall. By protruding from the side wall, the prism can be prevented from contacting the side wall, and the contact area of the prism can be reduced, thereby reducing the contact area to avoid edge chipping and scratches. On the other hand, reducing contact can reduce the proportion of dirt, thereby effectively protecting the prism.
[0048] In some embodiments, the jig 300 is used to place a strip prism. The prism has two right-angled surfaces and one inclined surface. When placed in the placement hole 310a, the support plate at the bottom is used to support one right-angled surface of the prism, and the support block 301 contacts the other right-angled surface of the prism, and the inclined surface does not contact the side wall of the placement hole 310a. In this way, while ensuring support for the prism, it can also reduce the contact area between the jig 300 and the prism, thereby effectively protecting the prism.
[0049] See also Figure 2 The inner wall of the second base 200 has a support block 201 protruding from the inner wall, and the jig 300 is placed on the support block 201, that is, the jig 300 is placed on the support block 201 under the action of gravity. In this way, the jig 300 can be placed without a complicated installation structure. It should be understood that since multiple base components are stacked together and placed in the coating machine, the support blocks 201 are located at the four corners of the mounting cavity 200a, and the space occupied by the mounting cavity 200a is relatively small, which will not affect the prism coating in the next layer of the jig 300.
[0050] It is understandable that when the jig 300 is placed in the mounting cavity 200a, the outer wall of the jig 300 fits with the inner wall of the second base 200, or the gap between the two is small. In this way, the stability of the jig 300 during placement can be ensured, and the accuracy of the coating can be ensured.
[0051] In some embodiments, when multiple base assemblies are stacked, there is a gap between the upper surface of the second base 200 and the lower surface of the second base 200 of the adjacent base assembly. In this way, there is enough space to place the prism in the jig 300, and the prism on the jig 300 can be prevented from being scratched by the adjacent jig 300, thereby effectively protecting the prism.
[0052] On the other hand, due to sufficient space, it can also ensure that the prisms on each base component can be fully coated. Specifically, along the vertical direction, the spacing size is M, the thickness of the jig 300 is N, and M and N satisfy 2N≤M≤3N, that is, M can be N, 2.2N, 2.5N, 2.7N, 3N or any two of the above vertical ranges. In this way, not only can the structure of the entire jig 300 assembly be compact, but also the prisms on the jig 300 can be prevented from scratching with the adjacent jig 300, while ensuring that the prisms on each base component can be fully coated.
[0053] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
